JAMES WILLIAM CLEGG, OF OLDHAM, ENGLAND.

COMBING MACHINE.

Specification of Letters Patent.

Patented Aug. 1, 1922.

Application filed February 12, 1920. Serial No. 358,291.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

To all whom it may concern:

Be it known that I, James WILLIAM CLEGG, a subject of the King of Great Britain, residing at Soho Iron \Vorlrs, Oldham, in the county of Lancaster, England, have invented new and useful Improvements in Combing Machines, (tor which I have ob tained a patent in Great Britain, No. 117,048, application filed February 27, 1918), of which the following is specification.

My invention relates to improvements in combing machines and has for its object to improve the means for applyingpressure to the feed roller at each head of a cotton combing machine of that type of Nasmith comber in which a single teed roller is in contact with the cushion plate.

Hitherto it has been customary to weight the feed roller which bears on the lap as it passes over the nipperbridge or plate to the nippers by an arrangement of levers and springs and my invention consists in an improved combination and arrangement of springs.

In the drawings accompanying and forming part of this specification,

Fig. 1 is a plan view, broken away, of a machin embodying the present invention;

Fig. 2 is a vertical, sectional view of the machine shown in Fig. 1; and

Fig. 3 is a View similar to Fig. 2, but illustrating a modified form of the invention.

Referring first to Figs. 1 and 2, a designates a part of the frame of the machine, 7) the nipper bridge or plate, and c the feed roller between which and the bridge 6 the lap passes on its way to the nippers, and which feed roller is acted on by a pair of levers 2', each fulcrumed at one end on a stud j on the frame of the machine, and at the other end recessed to fit over a trunnion carried by the feed roller 0.

For maintaining the roller 0 under tension in contact with the nipper plate 5, in the present instance, I have provided a pair of simple levers g of the first order, each fulcrumed on a stud it and bearing at one end on one of the trunnion levers 7'. The levers g are held in contact with the levers 2' by means of a pair of coiled springs (Z, each hooked at one end into an opening in the rear end of its respective lever g and secured at its opposite end to a threaded rod d, which passes through an opening in the upper end of a curved or otherwise suitably shaped supporting bracket'm secured on a stud f, the lower end of said bracket resting on the frame of the machine. The rod d also passes through a V-shaped member lo, the apex of which is seated in a recess formed in the upper side of said bracket m, the rod being provided at its free end with a nut (Z by means of which the tension of the spring d may be adjusted.

In this improved arrangement the pull of the spring d is applied with increased leverage and consequently with greater weighting power to the feed roller 0.

Further, when it is necessary to relieve the weight as for example when it is desired to lift out the feed roller, it is only necessary to pull up the spring and take oil" the V piece 713 from the support m.

In the alternative improved arrangement illustrated in Fig. 3 the only difference between it and that already described is that the intermediate lever is dispensed with and the spring (Z connected directly to the trunnion lever i which is formed with an extension for this purpose.

What I claim as my invention and desire to secure by Letters Patent is 1. In a cotton comber, the combination of a lap feed roll, a pair of levers pivoted centrally of their length, a spring engaging one extreme end of each of said levers thereby to exert pressure through th opposite ends of the levers on the ends of said roll, means for adjusting the tension of said springs, and removable means for maintaining the adjusted tension of the springs.

2. In a cotton comber, the combination of a lap feed roll, a pair of levers pivoted centrally of their length, a spring engaging one extreme end of each of said levers thereby to exert pressure through the opposite ends of the levers on the ends of said roll, a threaded rod secured to each of said springs, a stationary support having an opening, for the passage of said rod, a nut on the free end of said rod, and a removable member between said nut and support.

In testimony whereof I have signed my name to this specification.

JAMES WILLIAM CLEGG.
